So I joined the Hogwarts Running Club this year (which you can check out here –> www.hogwartsrunningclub.com ) and they recently had a global event for all of us Gryffindors out there to exchange post cards. It was kind of like secret Santa, but with postcards and I was so happy when I got mine all the way from NYC!!!
I will definitely take part in an exchange like that again, and can only recommend it. It was so nice to get a real postcard and to send away some joy, too.
